Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wire binding tool for binding an object with a wire. More specifically, the present invention relates to a manual wire binding tool for binding a wire around a rebar or the like by pulling the wire in a loop and pulling the wire with a wire binding tool.

[0002]

[Prior art]

 The number of rebars used for civil engineering and concrete work in construction work is enormous, and it is a simple task to bind them by hand with wires, which is hard, inefficient, and of variable quality for workers. However, the cost is high and the improvement has been strongly demanded.

[0003]

[Problems to be solved by the invention]

 In view of such circumstances, an object of the present invention is to provide a wire binding tool capable of performing an inefficient binding work of a reinforcing bar or the like by hand using a wire with a simple operation in a light weight and in a short time. And

[0004]

[Means for Solving the Problems]

 The present invention relates to a wire bundling tool, wherein a rotor having a spiral groove on the outer periphery of a shaft, a C-shaped hook at the tip of the shaft, and a cylindrical stator tube having a detent protrusion on the inner wall of the tube. The stator is tied with a finger by the binding operator and pulled by the binding operator to twist the wire to bind the reinforcing bars and the like. If a large amount of torsion torque is required at the final stage of bundling, use multiple spiral grooves on the rotor to increase the size of the leads so that the tensile force does not increase. In addition, when the wire is thin and the torsional torque is small, the lead of the helical groove of the rotor is reduced to increase the number of twists, thereby improving the work efficiency.

[0005]

[Embodiment of the Invention] In the present invention, by using the above-mentioned tension type wire binding tool at the site such as a reinforcing bar binding work, advantages such as shortening of working time and reduction of fatigue of a work binder are obtained. I was able to. Hereinafter, the present invention will be described in detail with reference to examples.

【Example】

 FIG. 1 is a front sectional view of the wire binding tool of the present invention, and FIG. 2 is a cross-sectional view of a protruding portion in a cylinder of a stator of the wire binding tool of the present invention. In FIG. 1, a rotor 2 is rotatably disposed in a cylindrical stator 3. The rotor 2 includes a shaft 4, a C hook 5, a nut 6, a spring receiver 7, and a bolt 8. The male thread 5A of the C hook 5 is screwed into the female thread 4A of the shaft 4 and is prevented from rotating by the nut 6. A spring receiver 7 is attached to a lower portion of the shaft 4 with a bolt 8. A spiral groove 4B is formed on the outer periphery of the shaft 4. The convex portion 10A provided on the inner wall of the cylinder 10 is engaged with the spiral groove 4B to apply a rotational force to the shaft 4 to generate a torsion torque on the wire 13. The lead of the spiral groove 4B is determined by the required torsional torque. However, since the torsional torque in the initial stage of binding is generally small and a large torsional torque is required in the final stage, the lead of the spiral groove 4B is initially small. And increase the lead in the final stage. When the torsional torque is small, the lead of the spiral groove 4B in the initial stage of binding and the final stage is the same, and when the lead is made small, the number of revolutions increases and the efficiency is improved. In this case, the longer the number of spiral grooves 4B, the longer the life of the tool.

The stator 3 is composed of cylinders 10, 11 and 12, and the cylinders 11 and 12 are connected by connecting screws 13. The rotor 2 is normally in the retracted position by the spring 9, but when twisting the wire 14, it advances while rotating. For this reason, the end face of the spring 9 slides on the upper surface of the spring receiver 7 and is coated with a lubricant. In some cases, a thrust bearing may be provided between both parts.

Next, a method of using the wire binding tool 1 of the present invention will be described with reference to FIG. The wire 13 is hung on the rebars 15 and 16, and the wire is twisted by hand about one turn with both ends facing forward to form a loop. Next, when the C-type hook 5 of the wire binding tool 1 is put on the near side of the ring-shaped wire, and the stator 3 of the binding tool 1 is gripped with a finger and pulled forward, the rotor 2 rotates and twists the wire 13. A plurality of torsional bumps 13A are generated to fix the reinforcing bars 14,15. In this way, it is possible to bind rebar in a short time with simple operations. Note that there are various methods of wire application other than the above, but the description is omitted.

[0009]

[Effect of the invention]

 According to the present invention, it is possible to easily and quickly bind a reinforcing bar or the like with a tension-type wire binding tool, so that cost can be reduced. In addition, since the tool is lightweight and easy to operate, the fatigue of the worker is reduced, so that even girls can do it, which has a great effect in terms of securing labor. In addition, since the rebar assembling work is often performed in high places, the light weight of the above-mentioned tools and the simplification of the work can be said to be an epoch-making invention that greatly contributes to the industry in terms of safety.
